By Definition. A single board foot of lumber measures 1 inch thick, 12 inches wide and 12 inches long. The formula for calculating board feet is first to multiply thickness by width by length -- in inches. Then divide the total by 144 for the total board footage of a given board.
Calculating Board Feet. BOARD FEET: Board Feet is a measurement of lumber volume. A board foot is equal to 144 cubic inches of wood. Actually it's easy to calculate using the following formula: (Thickness x Width x Length) / 144 = Board Feet. Note: Lumber is specified by its rough size. This is why a 1x 4 board is actually 3/4 thick and a 2x 4 board is actually 1-1/2 thick. When you are figuring up board feet, keep in mind a waste factor.
